Maybe this is the cause i don't see it.

You are right. Beta includes improvements for Entity Developer and Entity Framework - features which are not supported in the Standard edition of dotConnect for Oracle (editions matrix).

Please try the following:
- uninstall your current dotConnect for Oracle;
- clear the Program Files\Devart\dotConnect and Program Files\Common Files\Devart folders;
- clear the bin and obj folders of your project;
- delete all Devart.* and policy.*.Devart.* files from the GAC;
- install dotConnect for Oracle Beta Trial;
- rebuild your project.
The 6.30 Beta Trial version of dotConnect for Oracle is a fully working version during 30 days period. Trial period starts after the first install of dotConnect for Oracle 6.x Trial on your workstation.
